Selecting a Model of Supersymmetry Breaking Mediation (2009)
AbdusSalam, S. S., Allanach, B. C., Dolan, M. J., Feroz, F., Hobson, M. P.
We study the problem of selecting between different mechanisms of supersymmetry breaking in the Minimal Supersymmetric Standard Model using current data. We evaluate the Bayesian evidence of four...
Fitting the Phenomenological MSSM (2009)
AbdusSalam, S. S., Allanach, B. C., Quevedo, F., Feroz, F., Hobson, M.
We perform a global Bayesian fit of the phenomenological minimal supersymmetric standard model (pMSSM) to current indirect collider and dark matter data. The pMSSM contains the most relevant 25...
Are BR(b->s gamma) and (g-2)_muon consistent within the Constrained MSSM? (2009)
Feroz, F., Hobson, M. P., Roszkowski, L., De Austri, R. Ruiz, Trotta, R.
We employ two different statistical tests to examine whether, in the framework of the Constrained MSSM, the experimentally determined values of BR(b->s gamma) and the anomalous magnetic moment of the...
Bayesian optimal reconstruction of the primordial power spectrum (2008)
Bridges, M., Feroz, F., Hobson, M. P., Lasenby, A. N.
The form of the primordial power spectrum has the potential to differentiate strongly between competing models of perturbation generation in the early universe and so is of considerable importance....
Feroz, F., Hobson, M. P., Zwart, J. T. L., Saunders, R. D. E., Grainge, K. J. B.
We present a Bayesian approach to modelling galaxy clusters using multi-frequency pointed observations from telescopes that exploit the Sunyaev--Zel'dovich effect. We use the recently developed...
Cluster detection in weak lensing surveys (2008)
Feroz, F., Marshall, P. J., Hobson, M. P.
We present an efficient and robust approach for extracting clusters of galaxies from weak lensing survey data and measuring their properties. We use simple, physically-motivated cluster models...
The impact of priors and observables on parameter inferences in the Constrained MSSM (2008)
Trotta, R., Feroz, F., Hobson, M. P., Roszkowski, L., De Austri, R. Ruiz
We use a newly released version of the SuperBayeS code to analyze the impact of the choice of priors and the influence of various constraints on the statistical conclusions for the preferred values...
MultiNest: an efficient and robust Bayesian inference tool for cosmology and particle physics (2008)
Feroz, F., Hobson, M. P., Bridges, M.
We present further development and the first public release of our multimodal nested sampling algorithm, called MultiNest. This Bayesian inference tool calculates the evidence, with an associated...
Bayesian Selection of sign(mu) within mSUGRA in Global Fits Including WMAP5 Results (2008)
Feroz, F., Allanach, B. C., Hobson, M. P., AbdusSalam, S. S., Trotta, R., Weber, A. M.
We study the properties of the constrained minimal supersymmetric standard model (mSUGRA) by performing fits to updated indirect data, including the relic density of dark matter inferred from WMAP5....
The Arcminute Microkelvin Imager (2008)
Barker, R. W., Biddulph, P., Bly, D., Boysen, R. C., Brown, A. R., ...
The Arcminute Microkelvin Imager is a pair of interferometer arrays operating with six frequency channels spanning 13.9-18.2 GHz, with very high sensitivity to angular scales 30''-10'. The telescope...
AMI limits on 15 GHz excess emission in northern HII regions (2007)
Scaife, A. M. M., Hurley-Walker, N., Davies, M. L., Duffett-Smith, P. J., Feroz, F., Grainge, K. J. B., ...
We present observations between 14.2 and 17.9 GHz of sixteen Galactic HII regions made with the Arcminute Microkelvin Imager (AMI). In conjunction with data from the literature at lower radio...
